Do you know the characteristics and advantages of powder metallurgy technology?
With the continuous development of national industrial technology, the traditional casting process of powder metallurgy has been unable to meet the needs of modern industry, so now the parts and components used in many fields need to be produced by high-tech means, however, powder metallurgy is this high-tech process. How much do you know about the characteristics and advantages of powder metallurgy process? Let's follow zhongwei's precision knitting to have a look.
1： Characteristics of powder metallurgy process
Powder metallurgy has a series of characteristics in technology and economy. Powder metallurgy is not only a material manufacturing technology, but also a material processing technology. For material manufacturing, powder metallurgy can produce materials with special properties that cannot be produced by ordinary melting and casting methods: it can control the porosity of materials and products, such as: powder metallurgy porous materials, oil-bearing, etc; Refractory metal materials and products are mainly made by powder metallurgy.
2： Advantages of powder metallurgy process
1: Most refractory metals and their compounds, pseudoalloys and porous materials can only be manufactured by powder metallurgy.
2: Because the powder metallurgy method can be pressed into the final size of the compact, without or little need for subsequent mechanical processing, it can save metal and reduce product costs. When powder metallurgy method is used to produce products, the metal loss is only 1%~5%, while when general melting and casting method is used, the metal loss may reach 80%.
3: Because the powder metallurgy process does not melt the material in the material production process, it is not afraid of the impurities that may be brought by the mixing of deoxidizer, while sintering is generally carried out in vacuum and reducing atmosphere, and it is not afraid of oxidation, nor will it cause any pollution to the material, so it is inherently possible to produce high-purity materials.
4: The powder metallurgy method can ensure the correctness and uniformity of the material composition ratio.
5: Powder metallurgy is suitable for producing a large number of products of the same shape, especially gear and other products with high processing costs. Manufacturing by powder metallurgy can greatly reduce production costs.
To sum up, it is the introduction of the characteristics and advantages of powder metallurgy technology. I hope that this article can let you have more understanding and understanding.
